6. NORMAL AND SAFE OPERATION

6.1. FUNCTION

The uninterruptible power supply (UPS) is connected between the mains and the electrical
load. It protects the load from mains interruptions and power failures.
On-line Principle
70-NET operates according to the on-line principle. In on-line operation, the
alternating voltage of the mains is converted into direct voltage. This DC
voltage is used to supply the inverter. The inverter converts the direct volt-
age into interference-free alternating voltage at a fixed frequency and ampli-
tude, from which are supplied the connected loads. This protects the load
from mains supply disturbances and provides a secure supply for electrical
loads (PCs, network servers, multi-console systems).
In case of a mains failure, the batteries provide uninterrupted power to the loads for a given
period, dependent on battery capacity and connected load.
Battery management
The battery is charged and discharged, as well as monitored, using a dedicated microproc-
essor control. This ensures battery lifetime is maximised. For details, see "Special features"
on page 27.
Overload capacity
In the event of overload (e.g. > 150 % of nominal load) or inverter failure, the load is sup-
plied directly by the mains supply via the automatic bypass. As soon as the system returns
to normal operating conditions, it automatically switches back to inverter operation.
Communication
The UPS offers several interfaces for communication with computers. Further information
is included in "Interfaces" on page 23.

6.2. SPECIAL FEATURES

Safe and reliable operation
• Real on-line functioning, i.e. complete de-coupling of the load from all anomalies in
the mains supply

tor control, highest flexibility and more.
• Electronic bypass increases the reliability of the electrical supply
Easy installation and operation
• Parameterisation using bundled PC software
• No requirement for presence of Operator during normal operation
• Simple LCD provides clear indication of status, load and battery quality, clear operat-
ing and display concept
• Event memory for fault analysis
• Fault display and audible signal
Battery management
• Automatic battery management ensures maximum battery life
• Automatic battery circuit test
• Temperature-dependent charging
Environment, EMC
